Overview
IORiver is a MultiCDN platform that enables businesses to manage multiple CDN局
System: Content Delivery Networks (CDNs) simultaneously, ensuring high availability and performance without the complexity of managing each CDN separately. Founded in 2024 by former Akamai engineers Edward Tsinovoi and Michael Hakimi, IORiver is based in Tel Aviv, Israel, and serves industries like SaaS, online retail, streaming media, and finance. The platform handles over 100 petabytes of traffic monthly, offering a unified interface for configuring edge services like WAF, rate limiting, and edge computing across multiple providers. It integrates with major CDNs such as Cloudflare, Akamai, Fastly, Edgio, and Amazon CloudFront. IORiver focuses on simplifying MultiCDN adoption for businesses needing global content delivery with minimal operational overhead.
Viblast was a Bulgaria-based company founded in 2013 that specialized in peer-to-peer (P2P) video streaming solutions, offering Viblast PDN and Viblast Player for live and on-demand video delivery. It served broadcasters, content providers, and CDNs, leveraging WebRTC and HTML5 to enable plugin-free HLS and MPEG-DASH playback. The company aimed to reduce bandwidth costs and improve stream quality for high-concurrency live streams. As of 2023, Viblast is reported as out of business, with no active services or official website available.
Network & Architecture
IORiver does not operate its own CDN infrastructure but orchestrates traffic across multiple third-party CDNs, including
Akamai,
Cloudflare,
Fastly,
Edgio,
Amazon CloudFront,
G-Core, and
Microsoft Azure. Its Virtual Edge solution routes traffic to optimal CDN providers based on geolocation, traffic type, or cost, achieving 99.999% availability. The platform supports global content delivery with no specific POP count disclosed, relying on the combined footprints of integrated CDNs. It uses a Multi-DNS approach for resilient routing, avoiding single points of failure. Regional strengths depend on the chosen CDN providers, with flexibility to include local CDNs for markets like India or China.

Pricing
IORiver operates on a pay-as-you-go (PAYG) model, with pricing based on traffic volume and bundled services like WAF and analytics. No public per-GB pricing is available, and costs vary depending on the mix of CDN providers used. IORiver negotiates wholesale agreements with CDNs to reduce costs, but specific pricing details are not disclosed on their website. Potential users should contact IORiver directly for quotes. No free tier or trial details are publicly listed.
Integrations & DevEx
IORiver supports
Terraform for infrastructure-as-code, enabling automated configuration of multi-CDN setups. It offers REST, Python, and Go APIs for programmatic control, integrating seamlessly with CI/CD pipelines. Real-time logs and analytics via GlobalView provide insights into traffic patterns and performance. Migration tools simplify switching CDNs by importing configurations and testing providers with minimal traffic initially. The platform supports integration with major CDNs like
Akamai,
Cloudflare, and
Amazon CloudFront, reducing setup complexity.
